Playing with the iPaq. Wrote some nice feature extraction
code for FPU-less machines. Somewhat unsurprisingly, it's
three times slower on my P3 laptop. (but 80 times faster on
the iPaq)

Discovered a nasty bug in the iPaq audio driver, leading to
a kernel oops. Predictably, select(2) was broken.
Sent off patches. No reply. You'd think that a patch that
changes a grand total of 4 lines, and fixes an oops, would
get a bit of priority in people's mailboxes. You'd think wrong.
